WANTED: Magic: The Gathering commons/uncommons

I have a young family member getting into MTG, I'm looking to acquire some basic cards to jumpstart their collection. If modern players are anything like when I was playing, you have boxes and boxes of extra commons/uncommons piled in your closet. I'm looking for more modern cards - Ixalan and newer, mostly, but if you have some older ones, I can still work with that. Please let me know approximately how many cards you are trying to sell, what sets they are from, and what price you are looking for.
